Title: Picture reader
Inventor: FUKAZAWA MOTOMU
IPC: H04N1/10
Filed: 1989-06-28
Abstract: PURPOSE:To prevent the blooming phenomenon of a photoelectric conversion element by using a diffusing member attachably and detachably arranged in a optical path according to the level of the reflectivity of an original. CONSTITUTION:The reflectivity of a part 6 to be read, placed on the surface of a original platen 8 is measured by a reflectivity detecting means 9. When the part 6 to be read of a high reflectivity is read based on an output signal from the means 9, the diffusing member 7 is inserted between the part 6 to be read and the original platen 8. Then, the part 6 to be read is irradiated with diffusing light and illumination effect is positively lowered. Thus, the quantity of light which is made incident on the surface of a picture reading means 4 by a projecting lens 3 is decreased, and the photoelectric conversion element is prevented from blooming. Moreover, an incident angle from a light source 1 to the part 6 to be read is set to be <=40 deg., and it is eliminated that normal reflection light from the part 6 to be read is made incident on the means 4, whereby reading precision is improved.

Title: Flow rate controller
Inventor: DANKAN EMU TOORU
IPC: B67D3/00
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To realize a flow rate control reducing or removing spray on shutting off a fluid, by providing a specified face which is axially transferable relatively against an air outlet and a regulating orifice and providing a protrusion arranged in the upper zone of the regulating orifice, on the face. SOLUTION: When a transferring element 5 rotates by a tangential force acting on a protrusion, the lower horizontal face 14 and the upper horizontal face 21 separate from each other. The protrusion or a bulge 25 transfers on the upper zone of a regulating orifice 7 by the separating motion. When the lower horizontal face 14 and the upper horizontal face 21 approach each other, impulse waves generate in the fluid between both faces. These impulse waves are pushed back from the zone of regulating orifice by the protrusion or the bulge 25 provided with a beveled part 26. As a result, when the lower horizontal face 14 and the upper horizontal face 21 are positioned to contact each other, the fluid impulse waves can not approach the regulating orifice 7. And hence, spray is reduced or removed.

Title: Recognizing circuit for remaining capacity of battery
Inventor: ISAKA ATSUSHI
IPC: G01R31/36
Filed: 1983-09-14
Abstract: PURPOSE:To recognize the remaining capacity of a battery by employing discharge by a normal load and instantaneous discharge by a large load in combination. CONSTITUTION:A monostable multivibrator MV1 is triggered to turn on a transistor (TR) Q1, and put a peak holding circuit PH1 in operation, and the lower- limit voltage value of the battery BT during discharge by the normal load L1 is held in the circuit PH1. Further, the upper-limit voltage value of the battery BT which is not unloaded after the discharge by the load L1 is completed is held by a peak holding circuit PH2 associated operatively with a monostable multivibrator MV2 triggered at the following fall of the output of the monostable multivibrator MV1. Similarly, a peak holding circuit PH3 holds the lower-limit voltage value of the battery BT during the instantaneous discharge by the large load L2. The held values in those circuits PH1-PH3 are processed by a microcomputer 3 to multiply dropping values of battery voltages in the normal load discharge and instantaneous large load discharge by a desired weight coefficient and also sum up the products, so that the remaining capacity of the battery is recognized with high precision regardless of individual conditions of the different loads by employing both loads in combination.
